Question

記n項正項數(shù)列為a₁,a₂,…,a_n,Π_n為其前n項的積,定義為“疊加積”.如果有2 006項的正項數(shù)列a₁,a₂,…,a_{2 006}的“疊加積”為2^{2 007},則有2 007項的數(shù)列2,a₁,a₂,…,a_{2 006}的“疊加積”為(    )

A.2 007²                                             B.2^{2 007}

C.2 006^{2 007}                                      D.2 007^{2 006}

Answer 1

B

解析:

==2^{2 007}.

故應(yīng)選B.
